Defensive publication

ABSTRACT

POLYESTERS OF 2,2,4-TRIMETHYLPENTANE1,3-DIOL, AN ETHYLENICALLY UNSATURATED ACID OR ANHYDRIDE SUCH AS MALEIC, AND A POLYHYDRIC COMPOUND CONTAINING AT LEAST THREE HYDROXYL GROUPS ARE USED WITH A VINYL MONOMER SUCH AS STYRENE, WHICH IS A SOLVENT FOR THE POLYESTER, AS A GENERAL PURPOSE RESIN. THE POLYESTER IS PREPARED WITH RELATIVELY LITTLE DECOMPOSITION OF THE DIOL. THE UNSATURATED POLYESTER-VINYL MONOMER SOLUTION MAY BE USED AS A GENERAL PURPOSE RESIN FOR CASTINGS, COATINGS AND THE LIKE BY COPOLYMERIZATION USING METAL PROMOTED, ORGANIC PEROXIDE INITIATOR SYSTEMS AT ROOM TEMPERATURES. THE POLYOL IS PRESENT IN AMOUNTS OF FROM ABOUT 1 TO ABOUT 30 MOLE PERCENT, BASED ON THE COMBINED MOLES OF THE POLYOL AND DIOL. THE POLYESTER IS PRESENT IN THE COMPOSITION IN AMOUNTS BETWEEN ABOUT 40% AND ABOUT 70% AND THE VINYL MONOMER IN AMOUNTS OF BETWEEN ABOUT 60% AND AND 30%, BY WEIGHT BASED ON THE TOTAL OF THE COMPOSITION.

PUBLISHED APRIL 17, 1973 T909,024 POLYMERIC COMPOSITIONS James L. Suggs, 4241 Maplewood St., Kiugsport, Tenn. 37660 Filed Oct. 2, 1972, Ser. No. 294,416 Int. Cl. C08g 17/10 US. Cl. 260-861 No Drawing. 13 Pages Specification Polyesters of 2,2,4-trimethylpentane-l,3-diol, an ethylenically unsaturated acid or anhydride such as maleic, and a polyhydric compound containing at least three hydroxyl groups are used with a vinyl monomer such as styrene, which is a solvent for the polyester, as a general purpose resin. The polyester is prepared with relatively little decomposition of the diol. The unsaturated polyester-vinyl monomer solution may be used as a general purpose resin for castings, coatings and the like by copolymerization using metal promoted, organic peroxide initiator systems at room temperatures. The polyol is present in amounts of from about 1 to about 30 mole percent, based on the combined moles of the polyol and diol. The polyester is present in the composition in amounts between about 40% and about 70% and the vinyl monomer in amounts of between about 60% and about 30%, by weight based on the total weight of the composition.
